Electron version to update DOM with API info

[parnmatt]

I remember the later versions of the pre-electron version displaying information like when you changed activities etc; as well as updating Discord.

I think it would be nice to bring that back into the electron app; as right now it's just a blank webpage; and the only way I know it's working is seeing if Discord has updated my playing status

Great idea :)
